One-stage neonatal repair of complex aortic arch obstruction or interruption. Recent experience at Texas Children's Hospital.
The optimal surgical approach for complex aortic coarctation or an interrupted aortic arch with associated intracardiac defects is not universally agreed upon. We reviewed our experience with 18 consecutive patients (10 with coarctation, 8 with interrupted aortic arch) undergoing a 1-stage repair through median sternotomy between September of 1995 and February of 1997. Age at operation ranged from 3 days to 3 months (mean 23 days) and weight ranged from 1,700 g to 5,100 g (mean 3,350 g). Under hypothermic circulatory arrest, the aortic arch was reconstructed using native tissue-tissue anastomoses, and coexisting intracardiac anomalies were repaired by standard techniques. All patients survived the procedure and were ultimately discharged from the hospital. There were 2 late deaths in the interrupted aortic arch group, 1 during reoperation for subaortic stenosis and the other from noncardiac causes 5 months after discharge. Another interrupted aortic arch patient required a Ross-Konno procedure 8 months later. There has been no recoarctation among the 16 survivors. Thus a 1-stage repair for complex aortic arch obstruction in neonates can be accomplished with low operative risk, although long-term outcome is strongly influenced by the presence of subaortic obstruction.
